Abstract

A frame for a transport trailer has two lateral longitudinal members which are detachably connected to a plurality of cross members and which have a double T-member-like profile, at least one web out of the upper and lower cross web of which profile is constructed as a box profile which is open in a continuous longitudinal slot on the side facing away from the longitudinal member and located in its longitudinal axis. In order to substantially simplify the design, each longitudinal member (1) consists of two identical member shells which are joined together in a mirror-inverted manner and connected securely to one another at their faces (111, 121) forming the longitudinal web (111, 121) of the longitudinal member (1), the longitudinal slot (13; 14) of the box profile (113; 123) being formed on the two member shells by means of angled, continuous, short clips (114; 124) which project into the box profile (113; 123). <IMAGE>

Description

Die Erfindung betrifft einen Rahmen für einen Transportanhänger zum Transport von Kraftwagen, Booten und dergleichen mittels eines Kraftfahrzeuges, mit zwei seitlichen Längsträgern und mehreren mit den Längsträgern lösbar verbundenen Querträgern, wobei die Längsträger ein doppel-T-trägerähnliches Profil aufweisen, von dessen oberem und unterem Quersteg aber mindestens einer als Kastenprofil ausgeführt ist, das auf der dem Längsträger abgewandten, in dessen Längsachse liegenden Seite in einem durchgehenden Längsschlitz geöffnet ist.The invention relates to a frame for a transport trailer for transporting motor vehicles, boats and the like by means of a motor vehicle, with two side longitudinal members and a plurality of cross members detachably connected to the longitudinal members, the longitudinal members having a double-T-beam-like profile, of its upper and lower Cross bar but at least one is designed as a box profile, which is open in a continuous longitudinal slot on the side facing away from the side member and lying in its longitudinal axis.

Derartige Rahmen werden im allgemeinen in Schweißkonstruktion hergestellt, so daß der gesamte Rahmen erst danach mit einem Korrosionsschutz versehen werden kann. Eine solche Konstruktion hat mehrere Nachteile. Zunächst erfordert die Schweißverbindung der Quer- und Längsträger einen erheblichen Personal- und Kostenaufwand, zumal wegen der Benutzung des Rahmens im Straßenverkehr hohe Anforderungen an die Ausführung der Schweißarbeiten zu stellen sind. Darüber hinaus ist aber auch die Handhabung des Rahmens bei den nachfolgend aufzubringenden Arbeiten zum Korrosionsschutz umständlich, wobei sich der Rahmen gegebenenfalls sogar wegen der unvermeidlichen Wärmespannungen, z.B. während eines Feuerverzinkens, verziehen kann und dann mühsam gerichtet werden muß.Such frames are generally manufactured in a welded construction, so that the entire frame can only be provided with a corrosion protection afterwards. Such a construction has several disadvantages. First of all, the welded connection of the cross members and side members requires considerable expenditure of personnel and money, especially since the use of the frame in road traffic places high demands on the execution of the welding work. In addition, however, the handling of the frame is also cumbersome in the corrosion protection work to be carried out subsequently, the frame possibly even being damaged due to the inevitable thermal stresses, for example during a Hot dip galvanizing, warping and then laboriously straightening.

Es ist auch bereits vorgeschlagen worden, Längs- und Querträger miteinander zu verschrauben. Dazu sind an den Verbindungsstellen der Querträger in den Längsträgern laschenartige Verbindungsstücke vorgesehen, die etwa rechtwinklig vom Längsträger abstehen und an denen die Querträger angeschraubt sind. Die Verbindungsstücke sind an mehreren Stellen formschlüssig am Längsträger befestigt; mit einer Lasche, die unter dem unteren Kastenprofil des Längsträgers an diesem anliegt, wird ein solches Verbindungsstück mit dem Längsträger verschraubt. Der Kopf einer zugehörigen Bolzenschraube befindet sich in einer schwalbenschwanzartigen Führung innerhalb des Kastenprofiles, deren Längsschlitz in bekannter Weise als Führung für den Schraubenbolzen dient. Eine solche Schraubverbindung hat den Vorteil, daß der Transportanhänger nach dem Baukastensystem in verschiedenen Größen und Ausführungen zusammengesetzt werden kann, wobei auch an eine Benutzung der schwalbenschwanzartigen Führung zur lösbaren Befestigung von Zusatzteilen für den Transportanhänger zu denken ist. Die Herstellung eines solchen Längsträgers etwa im Strangpreßverfahren ist aber wegen der unterschiedlichen Wanddicken und der eingeformten Kastenprofile nicht einfach.It has also already been proposed to screw the longitudinal and transverse beams together. For this purpose, tab-like connecting pieces are provided at the connecting points of the cross members in the side members, which protrude approximately at right angles from the side members and to which the cross members are screwed. The connectors are positively attached to the side member in several places; such a connecting piece is screwed to the side member with a tab that lies under the lower box section of the side member. The head of an associated stud screw is located in a dovetail-like guide within the box profile, the longitudinal slot of which serves in a known manner as a guide for the screw bolt. Such a screw connection has the advantage that the transport trailer can be assembled in various sizes and designs according to the modular system, with the use of the dovetail-like guide for releasably fastening additional parts for the transport trailer also being considered. However, the production of such a longitudinal beam, for example in the extrusion process, is not easy because of the different wall thicknesses and the molded-in box profiles.

Die Erfindung hat sich demzufolge die Aufgabe gestellt, einen Längsträger für einen Rahmen der eingangs näher bezeichneten Art wesentlich zu vereinfachen, ohne die Vorteile aufzugeben, die durch lösbar miteinander verbundenen Längs- und Querträgern gegeben sind.The invention has therefore set itself the task of significantly simplifying a side member for a frame of the type specified in the introduction, without giving up the advantages that are provided by detachably connected side members and cross members.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß der Längsträger insgesamt aus zwei spiegelbildlich zusammengesetzten, gleichen Trägerschalen besteht, die an ihren den Längssteg des Längsträgers bildenden Flächen fest miteinander verbunden sind, und daß der Längsschlitz des Kastenprofiles durch in das Kastenprofil hineinragende, abgewinkelte, durchgehende, kurze Laschen an beiden Trägerschalen gebildet wird, und daß ferner der Längssteg des Längsträgers ein oder mehrere geschlossene Kastenprofile enthält, die in der Längsachse des Längsträgers liegen und beispielsweise durch Sicken in den Trägerschalen gebildet werden.According to the invention the object is achieved in that the longitudinal beam consists of a total of two mirror-image assembled, the same support shells, which on their Longitudinal web of the side member forming surfaces are firmly connected to each other, and that the longitudinal slot of the box section is formed by protruding, angled, continuous, short tabs on both carrier shells, and that the longitudinal web of the side member contains one or more closed box sections, which in lie along the longitudinal axis of the longitudinal beam and are formed, for example, by beads in the carrier shells.

Auf diese Weise wird der Längsträger aus sehr einfachen und auch einfach herzustellenden Bauelementen zusammengesetzt, die in beliebiger Weise, beispielsweise durch Abkanten, hergestellt werden. Werkstoffanhäufungen treten nicht auf, vielmehr lassen sich die Trägerschalen in durchweg gleicher Wanddicke halten; mehrachsige Spannungszustände bei Wärmebehandlungen werden so vermieden.In this way, the longitudinal member is composed of very simple and also easy-to-produce components that are manufactured in any way, for example by folding. Material accumulations do not occur, rather the carrier shells can be kept with the same wall thickness throughout; Multi-axis stress states during heat treatments are avoided.

Besonders vorteilhaft ist es, wenn in dem offenen Kastenprofil ein mit seinen Gurten die Laschen überragendes, U-trägerähnliches Klemmstück angeordnet ist, das zur verdrehsicheren Lagerung von bolzenartigen Verbindungselementen, wie Bolzenschrauben oder dergleichen dient, deren Bolzen durch den Längsschlitz des Kastenprofiles nach außen ragen; es ist nun möglich, daß mit Hilfe der Verbindungselemente die Querträger an den Längsträgern befestigt sind. Andererseits ist es auch denkbar, daß mit Hilfe der Verbindungselemente Achsflansche für die Achsschwingen von Kraftfahrzeugen an den Längsträgern befestigt sind. Damit ist eine einwandfreie, drehfeste Lagerung der erforderlichen Verbindungselemente erreichbar, und ferner ist eine flächige Anpressung des für die Anbindung beispielsweise der Querträger verwendeten Kastenprofiles gewährleistet, so daß Verformungen am Profil des Längsträgers weitgehend vermieden werden. Dabei ist die Ausnützung des Kastenprofils für die Anbindung anderer Bauelemente nicht auf dessen am Längsträ-ger untere Ausführung beschränkt; auch das obere Kastenprofil kann in gleicher Weise für derartige Aufgaben herangezogen werden. Damit ist der erfindungsgemäße Rahmen aber weitaus universeller einsetzbar; beispielsweise können zwei Längsträger übereinander angeordnet sein.It is particularly advantageous if a U-beam-like clamping piece, with its straps projecting beyond the straps, is arranged in the open box section, which is used for the torsion-proof mounting of bolt-like connecting elements, such as stud bolts or the like, the bolts of which protrude through the longitudinal slot of the box section; it is now possible for the cross members to be fastened to the longitudinal members with the aid of the connecting elements. On the other hand, it is also conceivable that with the aid of the connecting elements, axle flanges for the axle swing arm of motor vehicles are fastened to the side members. A flawless, non-rotatable mounting of the required connecting elements can thus be achieved, and furthermore a flat contact pressure of the box profile used for the connection, for example, of the cross members is ensured, so that deformations on the profile of the longitudinal member are largely avoided. Here is the exploitation of the box profile for the Connection of other components is not limited to its lower version on the side member; the upper box profile can be used in the same way for such tasks. However, the frame according to the invention can thus be used far more universally; for example, two longitudinal beams can be arranged one above the other.

In den Figuren 1 und 2 der Zeichnung ist ein Transportanhänger gezeigt, wie er zum Transport von Kraftfahrzeugen branchenüblich ist. Sein Rahmen besteht aus Längsträgern 1 und Querträgern 2, die an ihren Kreuzungsstellen 3 miteinander lösbar starr verbunden sind. Deichseln 4 können dabei in beliebiger Weise am Rahmen vorgesehen sein. Die übrigen Bauteile des Transportanhängers stehen mit der Erfindung nicht im Zusammenhang, sind zwar teilweise der besseren Übersicht halber eingezeichnet, im übrigen aber ohne Bezugszeichen belassen; ihre Ausführung und Anordnung ist dem Fachmann geläufig.1 and 2 of the drawing show a transport trailer as is customary in the industry for the transport of motor vehicles. Its frame consists of side members 1 and cross members 2, which are detachably rigidly connected to each other at their crossing points 3. Drawbars 4 can be provided on the frame in any way. The other components of the transport trailer are not related to the invention, are shown partly for the sake of clarity, but are otherwise left without reference numerals; their execution and arrangement is familiar to the person skilled in the art.

Figur 3 zeigt einen vergrößerten Profilquerschnitt durch einen erfindungsgemäßen Längsträger 1 an einer Kreuzungsstelle 3 mit einem Querträger 2. Der Längsträger 1 ist aus zwei Trägerschalen 11 und 12 zusammengesetzt, die im Bereich der Flächen 111 und 121 miteinander verschweißt sind. Die Flächen 111 und 121 bilden gemeinsam den Längssteg 111; 121 des Längsträgers 1. Zur Verstärkung des Längsträgers 1 bei Durchbiegung um seine senkrechte Achse ist ein geschlossenes Kastenprofil 112; 122 mittig im Längssteg 111; 121 vorgesehen.FIG. 3 shows an enlarged profile cross section through a longitudinal beam 1 according to the invention at a crossing point 3 with a cross member 2. The longitudinal member 1 is composed of two carrier shells 11 and 12 which are welded together in the area of the surfaces 111 and 121. The surfaces 111 and 121 together form the longitudinal web 111; 121 of the side member 1. To reinforce the side member 1 when it bends around its vertical axis, a closed box section 112; 122 centered in the longitudinal web 111; 121 provided.

Der obere und der untere Gurt des Längsträgers 1 sind je als offenes Kastenprofil 113; 123 ausgeführt, offen nach oben bzw. nach unten durch je einen Längsschlitz 13 bzw. 14, der durch abgewinkelte Laschen 114 bzw. 124 ausgebildet wird, die aus den äußeren Gurtblechen 115 bzw. 125 so abgeleitet sind, daß sie in das Innere der Kastenprofile 113; 123 parallel zur Hauptachse des Längsträgers 1 ragen.The upper and lower belt of the longitudinal beam 1 are each as an open box profile 113; 123 executed, open upwards or downwards through a longitudinal slot 13 or 14, which is formed by angled tabs 114 and 124, which are derived from the outer belt plates 115 and 125 so that they into the interior of the box profiles 113; 123 project parallel to the main axis of the longitudinal member 1.

Ein Klemmstück 5 aus einem U-Profil dient als Widerlager für Verbindungselemente 6, die hier in Form von Sechskant-Bolzenschrauben ausgeführt sind. Der zugehörige Schraubenkopf ist am Klemmstück 5 festgeschweißt und damit verdrehsicher, so daß der Längsträger 1 tatsächlich problemlos mit dem Querträger 2 verschraubt werden kann.A clamping piece 5 made of a U-profile serves as an abutment for connecting elements 6, which are designed here in the form of hexagon bolts. The associated screw head is welded to the clamping piece 5 and thus secured against rotation, so that the side member 1 can actually be screwed to the cross member 2 without any problems.

In der Figur 4 schließlich ist anstelle eines Querträgers 2 nunmehr ein Achsflansch 7 mit dem Längsträger 1 verbunden. Das Verbindungselement 6 entspricht der Sechskant-Bolzenschraube der Figur 3, ist aber kürzer.Finally, in FIG. 4, instead of a cross member 2, an axle flange 7 is connected to the longitudinal member 1. The connecting element 6 corresponds to the hexagon bolt of Figure 3, but is shorter.

Die Erfindung ist auf das dargestellte Ausführungsbeispiel keineswegs beschränkt. So ist beispielsweise die geometrische Ausführung des Längsträgers 1 weitgehend variabel; es kann etwa seine Gesamthöhe variieren und aufgrund der Biegefestigkeit nach den Enden hin abnehmen.The invention is in no way limited to the exemplary embodiment shown. For example, the geometric design of the longitudinal beam 1 is largely variable; its total height can vary and decrease towards the ends due to the flexural strength.
